In addition, the plasma metabolome and selected biomarkers (from dried blood spot), urinary metabolome (from collected urine), DNA damage (from dried blood spots, telomere length and mitochondrial DNA deletions, DNA base damage/oxidation, gamma H2AX DNA strand break assay), micronutrient analysis (from dried blood spot or capillary blood collection) and microbiome (sequencing metagenomics/Fecal Swabs) will be offered to participants as additional measurements, if funding or in-kind sponsoring is available.
